Liquid metal rotating flow under permanent magnetic system impact Academic Article uri icon

abstract

  • Magnetohydrodynamic liquid metal flow in a cylindrical vessel under the action of a system of rotating permanent magnets is examined. The described system allows to create various hydrodynamic structures and control their behaviour in a flexible way. Numerical three- dimensional modelling of the flow is carried out in an induction-free approximation. The results of the velocity field computations have been validated earlier and satisfactorily agree with experimental data obtained using ultrasound Doppler velocimetry. Introduction. For many years, rotating magnetohydrodynamic (MHD) flows are an object of theoretical, experimental and numerical studies with a wide range of applications in various fields from geophysics and astronomy to industrial processes. In laboratory and industrial applications such flows can be excited, for example, by rotating magnetic fields (RMF)[1–3] or by …
